Molecular phylogenetic systematics suggest that Tylenchida share an immediate ancestor with Cephalobina. This relationship has implications, contradicting classical views, for evolution of the stomatostylet and homology with the cephalobid stoma. Emerging evidence from comparative TEM and 3D modelling is the basis for hypothesising that the tylenchid stylet, specifically the cone and shaft, is ...

Noctuidonema dibolia n. sp., an ectoparasite of adults of the noctuid moth Mocis latipes (Guenée) is described. The differentiating characters are a club-shaped body with a subterminal vulva in the female, spicules with a reduced matrix and sheath and closely apposed dorsal and ventral arms in the male, very long stylet and conus, moderately prominent stylet knobs, a bluntly rounded head, and a...

We thank Dr. Dupanovic for his interest in our study. As mentioned in our manuscript,1 we chose the two stylet angles to be studied based on the most common angulations used by anesthesiologists in our local practice. The distal 60° angulation used at our centre and in the study was heavily influenced by an expert in airway management who described using a stylet shape that closely approximates...

OBJECTIVE Robotic cochlear implant electrode array insertion offers substantial potential advantages, namely repeatability and minimization of insertion forces, leading to decreased intracochlear trauma. Using such a robotic insertion tool, we sought to analyze force profiles during deployment of stylet-containing electrode arrays using either traditional insertion, in which the stylet is withd...

PURPOSE To compare the ease of tracheal intubation facilitated by the gum elastic bougie or the malleable stylet while applying cricoid pressure. METHODS Sixty American Society of Anesthesiologists I-III adult patients undergoing elective surgeries participated in this study. After induction of anesthesia with 2.5 mg x kg(-1) propofol and vecuronium 0.1 mg x kg(-1), the laryngeal view was ass...

Two new species of the "Aequales" of genus Gieysztoria were collected and described from an artificial lake on the Shenzhen University campus. Gieysztoria bimaculata n. sp., is distinguished based on two groups clavate pigmentations dorsally between the pharynx and intestine, and has a sclerotic stylet comprising a proximal girdle with 40-46 distal dagger-shape spines, thus has the maximum numb...

Paratylenchus shenzhenensis n. sp. was collected from the rhizosphere soil of Anthurium andraeanum in Shenzhen, Guangdong Province, China. The new species is characterized by having a female with a small body (249-302 μm), well developed stylet (17-21 μm), rounded head with four submedian lobes and lip-region with a slight depression at the oral area, small post-vulval uterine sac with a few ve...

The feeding apparatus of Pratylenchus penetrans (Cobb) Chitwood and Oteifa was studied by means of the electron microscope. The stomatostylet is composed of tooth, shaft, and basal knobs. The tooth and shaft are closely interlocked. The tooth forms the outer covering and the inner lining of the anterior half of the stylet, whereas the shaft extends from the basal knobs to the level of the style...

With great interest, we read the recent article by Sheta et al1 comparing performance of the Parker Flex-It stylet and GlideRite Rigid stylet for orotracheal intubation by Glidescope videolaryngoscope in patients with normal airways. They showed that the 2 stylets were equally effective for intubation when used by experienced operators, but the Parker Flex-It stylet was easier and less traumati...
